Freemius API (1.0)

Welcome to the Freemius API Documentation!

You can use our API to access Freemius API endpoints, which can get information on various aspects of Freemius.

  • Manage products.
  • Manage license verifications.
  • Create custom integration with your SaaS.

If you're using Freemius for a WordPress product, please check out our official SDK.

Operations

Update a deployment

Request

Update a specific deployed version of the product. This applies to WordPress products only. Use this endpoint to update the release_mode of a deployment to make it available to your customers.

Release Modes

Defined by the release_mode property, with the following possible values:

  • pending – The deployment is pending and not visible to customers. This is the default value.
  • beta – The deployment is in beta mode. Only customers with beta access will see this version.
  • released – The deployment is released and visible to all customers.

Additionally, WordPress plugins and themes support incremental releases and staged rollouts:

  • Incremental Release: Controlled via the is_incremental flag, incremental releases enforce sequential updates, requiring users to install designated intermediate versions before proceeding to newer ones.
  • Staged Rollout: Managed through the limit and percentage_limit flags, staged rollouts enable gradual deployment of updates to a subset of users, allowing for monitoring and issue resolution before full release.

Note: Incremental Release and Staged Rollout are not supported for templates and widgets.

Path
product_idinteger(int64)>= 1required

Create a deployment

Request

Upload a new version of the product (for WordPress products only). The endpoint supports only the multipart/form-data content type and expects two payloads: file and data.

  • file - The zip file containing the product. For WordPress plugins or themes this must contain the root directory.
  • data - Please omit this when deploying WordPress plugins and themes. In case of deploying templates and widgets, this needs to be a stringified JSON and must have the version and requires_platform_version properties.

An example of the data property:

{"version": "2.0.0", "requires_platform_version": "1.0.0"}

After you have created a deployment, please send another PUT request to the newly created version to update the release_status to either released or beta. The default value is pending which means none of the customers will be able to see the new version.

You can learn more about the deployment process here.
